[0020] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example:

[0022] like Figures 1 to 6 As shown, a long-lasting low-temperature resistant corrugated cardboard includes: cardboard 1; a fixing block 2 is symmetrically fixedly connected to the right end of cardboard 1; an insert strip 3 is symmetrically fixedly connected to the end of fixing block 2 away from cardboard 1; a fixing strip 4 is symmetrically fixedly connected to one end of fixing block 2 and located between two sets of insert strips 3; a locking block 5 is fixedly connected to the side of each set of fixing strips 4 that is far apart; the locking block 5 has a sloping structure design on both sides; a placement groove 6 is opened at the left end of cardboard 1 at a position corresponding to the fixing block 2; a locking post 7 is fixedly connected to the middle of the placement groove 6. The inside of the placement groove 6 is symmetrically fixed with baffles 8. The inner side wall of the baffles 8 is provided with slots 9 at positions corresponding to the locking posts 7. When it is necessary to assemble the cardboard 1, first, the two sets of cardboard 1 are placed flat on the ground, and then the insert strips 3 are inserted into the inside of the placement groove 6. First, the locking posts 7 will separate the two sets of fixing strips 4, and then the fixing strips 4 will come into contact with the baffles 8. As it continues to extend, the locking block 5 is inserted into the inside of the slot 9. At this time, the slot 9 will limit the locking block 5, realizing the splicing between the two sets of cardboard 1.

[0023] In this embodiment, the side of the insert 3 that is far away from each other has a sloping structure design. A sloping edge is provided on the inner side wall of the placement groove 6 at a position corresponding to the bottom end of the insert 3. A receiving platform 10 is fixedly connected to the bottom of the sloping edge, and a column 11 is fixedly connected to the top of the receiving platform 10. A slot is provided inside the fixing strip 4 at a position corresponding to the column 11. When the insert 3 enters the interior of the placement groove 6, the insert 3 will then contact the inner side wall of the placement groove 6, and at the same time, the bottom of the insert 3 will contact the receiving platform 10. Then the column 11 is inserted into the interior of the slot.

[0024] In this embodiment, a support column 12 is fixedly connected to the middle of the right end of the cardboard 1. A diamond-shaped block 13 is fixedly connected to the end of the support column 12 away from the cardboard 1. A square groove 14 is opened at the left end of the cardboard 1 at the position corresponding to the diamond-shaped block 13. Elastic strips 15 are symmetrically fixedly connected to the inner sidewall of the square groove 14. An inclined block 16 is fixedly connected to the side of the elastic strip 15 that is close to it. Then, the diamond-shaped block 13 will enter the interior of the square groove 14. Then, the diamond-shaped block 13 will contact the inclined block 16 and squeeze the elastic strip 15. When the inclined block 16 contacts the diamond-shaped block 13, the elastic energy stored in the elastic strip 15 will be reset, thereby increasing the contact points between the two sets of cardboard 1, so that no loosening will occur after splicing.

[0025] In this embodiment, the cardboard 1 is composed of face paper 17, corrugated core 18 and blocking layer 19. Face paper 17 is located on the upper and lower sides of cardboard 1, corrugated core 18 is located on the side where the two sets of face paper 17 are close to each other, and blocking layer 19 is located between corrugated core 18. Through the design of corrugated core 18 and blocking layer 19, the overall rigidity of cardboard 1 is effectively improved.

[0026] In this embodiment, the face paper 17 is composed of a first kraft paper layer 1701, a second kraft paper layer 1702, and a chemical fiber pulp layer 1703 from top to bottom. The first kraft paper layer 1701, the second kraft paper layer 1702, and the chemical fiber pulp layer 1703 are connected by adhesive. The chemical fiber pulp layer 1703 is hydrophobically treated. The combination of the first kraft paper layer 1701 and the second kraft paper layer 1702 with the chemical fiber pulp layer 1703 significantly improves the overall tear and puncture resistance. Furthermore, its surface isolates moisture, effectively solving the problem of strength reduction that easily occurs in the paperboard 1 at low temperatures.

[0027] Implementation Plan: The first kraft paper layer 1701 and the second kraft paper layer 1702, combined with the chemical fiber pulp layer 1703, significantly improve overall tear and puncture resistance. Furthermore, their surface isolates moisture, effectively addressing the strength reduction issue that easily occurs in cardboard 1 at low temperatures. When assembling cardboard 1, first, place the two sets of cardboard 1 flat on the ground. Then, insert the insert strip 3 into the placement slot 6. First, the locking post 7 separates the two sets of fixing strips 4, then the fixing strips 4 contact the baffle 8. Following this... As the process continues, the card block 5 is inserted into the card slot 9. At this time, the card slot 9 will limit the card block 5. Then, the insert strip 3 will contact the inner wall of the placement slot 6, and the bottom of the insert strip 3 will contact the receiving platform 10. Then, the column 11 is inserted into the slot. Then, the diamond block 13 will contact the inclined block 16 and squeeze the elastic strip 15. When the inclined block 16 contacts the diamond block 13, the elastic energy of the elastic strip 15 will be reset, thereby increasing the contact points between the two sets of cardboard 1, so that there will be no loosening after splicing.
